Auto ISO and the Fujifilm X-T3

Auto ISO and the Fujifilm X-T3


– Remember this? Film, actual film, (laughs) right. Oh, you couldn’t just
change ISO with every shot when you were dealing with film. No siree. It was the biggest pain in the butt. You had to actually take the film out and put another roll
in just to change ISO. You wouldn’t wind it all the way, but there’d be a problem
and then (grunts). I never wanna go back to those days. I love being able to
change ISO between shots. And you know what I love even more? Auto ISO. Yes, give it to me, yes, please, Auto ISO, roll intro. (upbeat music) Hi, everyone, welcome to pal2tech. Today, I’d like to focus on Auto ISO and how it works on Fuji Film cameras, specifically the X-T2, X-T3, and X-T4. Yeah, I just wanted to say X-T4. I figure, (laughs) it just felt so good. Anyway, let’s dig into Auto ISO. First thing you need to do
is make sure that your camera is set up to best use Auto ISO. So the first thing you need to do is put the ISO dial on
A, and I like to lock it. The next thing you wanna
do is go into your MENU in the BUTTON/DIAL SETTING and go down to where it
says ISO DIAL SETTING A AUTO and make sure that that is set to AUTO. That really trips up a lot of people, so make sure it’s set to AUTO if you wanna use Auto ISO here. Now that you have your
camera set to do Auto ISO, we need to go into the
three Auto ISO presets. The way you get there is
you go into MENU, CAMERA, ISO AUTO SETTING, and you will see the three presets right here. One little gotcha to keep in mind, if you happen to have the camera in video mode, that’s a problem because if you go into
the ISO AUTO SETTINGS, they will be grayed out. You see that, you see how it’s grayed out? But if you take this and put
it back into any other setting, you’ll see it is now available. These are three presets
that you can customize, and each one has three
parameters that you can adjust: Default Sensitivity, MAX Sensitivity, and MINIMUM Shutter Speed. This should really be called MINIMUM ISO, and it goes all the way up to 12800. Keep in mind that it will
not, and does not, include the extended ISO values of L and H. Can’t use those, all right? So the Auto ISO feature
only allows you a choice of one of the native ISO
ranges on the camera, basically the numbers
you see on the dial here that are not H and L. On the X-T3, I recommend
setting this DEFAULT to 160. If you have an X-T2 camera, set it to 200. The next one is MAX. SENSITIVITY, and here you are telling the camera the highest ISO you wanna use. And you need to choose wisely here because no matter what other settings you have on this camera, if you set a value here and you go out and you start shooting, your camera will never go beyond that. So a good starting place for this that I like to use is ISO 3200. And finally, we have
MINIMUM SHUTTER SPEED, and here you have two choices. First, you could set a firm value, such as one over 125 of a second, and if you do that,
you’re telling the camera, hey, don’t shoot at a slower shutter speed than the value I set here. Now, in addition to these firm set values, it also gives you the option called AUTO. This causes the camera
to automatically set the minimum shutter speed according to whatever focal length lens you have on the camera, right? So it will depend on the
type of lens you have. What it does is it
assigns the shutter speed based roughly, the keyword is roughly, on one over the focal length of the lens. Let’s test this out. I’m gonna go and set MAX. SENSITIVITY all the way up to 12800, got
that, I’ve got it in AUTO, I’m gonna go ahead and put
the camera in Auto mode, boom, okay. Now, I’m kinda looking around here. And as I sort of drop my light here, shutter speed is 34. For this 23-millimeter lens,
and I had it on Auto, right, it’s choosing a minimum
shutter speed of one over 34. There’s some weirdness that
goes on with these calculations because it’s not exactly one over the focal length of the lens. Why would you wanna use
Auto to begin with, okay? Well, let’s say you’re using
the 55 to 200 zoom, okay? And to avoid handheld camera shake blur, you need to use a different
minimum shutter speed depending upon where you have
this lens zoomed in, right? So if you have it at 55 millimeters, then you would have one set
of minimum shutter speed to avoid camera shake when
you’re holding the camera. But if you zoom all the way up to 200, you’re going to need
a faster shutter speed because you are now at a
higher focal range, right? So it depends, and that’s
why Auto was created. It reads the lens automatically and then adjusts the minimum
shutter speed of the camera based on whatever the
current focal length is that you happen to be zoomed in on. In theory, that’s what it is. But there’s some screwball things going on with Auto Minimum Shutter Speed that I’m not that thrilled with. First off, there’s no
way to tell the camera the specific multiplier to
use for the calculations. And second, what does approximately mean? I mean it’s not very clear. So who knows? Third and most problematic,
at least for me, is that the camera ignores
whether or not the lens has image stabilization built into it. That’s a big deal. So if you have a lens that has OIS, let’s say you got your
little switch on on OIS, it will allow you to shoot handheld at much slower shutter
speeds than non-OIS lenses. But the Auto Minimum Shutter Speed seems to really not
take this into account, and that’s a problem, at least for me. So with these variables
and how they work together, let’s talk about the
elephant in the room, okay? What happens when you
don’t have enough light? How does Auto ISO handle this and what does it do to your shutter speed? First, let’s say that you have the camera set to Auto everything. It’s got it set to Auto everything. If there’s not enough light, the camera will first try
to compensate for this by slowing down your shutter speed and opening up your aperture
to let in more light. And it will do this,
keeping the lowest ISO, that’s the default sensitivity that you’ve set in the preset. And if there’s still not enough light to properly expose the image, it will then start raising
the ISO in your camera until it reaches your ISO max setting. And once it hits that, it will never, and this is the key you need to know, once it hits that, it
will never go beyond that. And since your lens is now as wide open as it possibly can be, your camera then begins to
lower your shutter speed even beyond the original
minimum that you set. This is the biggest gotcha with Auto ISO on the Fuji Film camera because highest ISO really is highest ISO, and the camera will never
go beyond that, ever. But minimum shutter speed is more of a suggestion, right? It’s not a rule. And the camera will, and
does, break out of that and will lower your shutter speed which can result in a blurry photo. Same thing, if you have the
camera on aperture priority, and let me show you with a
real-life example here and now. I’m gonna choose DEFAULT
SENSITIVITY of 160, MAX. SENSITIVITY, I don’t want the ISO to go higher than 800, and my MIMINUM SHUTTER
SPEED is 1/30 of a second. I’m gonna open up the
lens all the way to two and aperture priority right here. I’ve got this set on Auto and
I’ve got this set on Auto. Now, if I’m trying to
take a picture with it, look at how my shutter speed, if it doesn’t get enough light, my shutter speed drops. You see that? It drops, look at that. So my ISO is 800. That was the maximum ISO I set. It will not go beyond 800 and it will happily lower my
shutter speed down to 1/15, resulting in a blurry shot, okay? So, how can you best use Auto ISO and what do I recommend that you do? Easy, simple, simple. You need to put the camera in
what I call D.W.A.T.I. mode. Don’t Worry About the ISO Mode, all right? And here is, (laughs)
D.W.A.T.I. mode is great for shooting kids, fast-moving action where you’re using, say, you’re
using a 90-millimeter lens and you just want that awesome control because I like to have control over both aperture and shutter speed but not always have to be fiddling with these dials constantly. So here’s how you do that. I go into my ISO AUTO SETTING, I set the DEFAULT SENSITIVITY to the lowest one on the camera,
so on the X-T3, that’s 160. On the X-T2, that would be 200. Next, I set the MAX. SENSITIVITY
all the way up to 12800. Again, I’d rather have a
grainy shot than a blurry one. Then I set my MINIMUM SHUTTER SPEED, it really doesn’t matter what you set here because we’re gonna take
control over the shutter speed. So I’m just gonna go
ahead and just to set it, I’m gonna put it at 1/60 of second. Now, here, what I do is
keep this dial in Auto. Okay, so I’m gonna take control
over this dial right here and I’m gonna say, hey, camera, do not go below over
1/60 of a second, okay? Then on my aperture, I’m
gonna take control of that because I want some beautiful
bouquet in the background and I’m gonna say, all
right, I want it at F2. So I’m controlling the aperture, I’m controlling the shutter speed, and I have this dial in Auto ISO. Now, I can go out and I can take pictures
to my heart’s content. And as you can see, look
out, it’s suggesting the ISO. If I aim it at something
bright, right, 160, 160. But if I aim it at
something darker, darker, it drops it down to 200 ISO. So it’s just auto-adjusting the ISO, and that is a really wonderful technique when you want a minimum of hassle, you wanna have some semblance of control over aperture and shutter speed, and you’re shooting RAW because what’s great is you
can bring those RAW files in and there is the whole
thing about ISO invariance, which I will talk about in a future video. Okay, here are some ways that I would like to
see Auto ISO improved, all of which I think could be done with firmware updates, okay? Fuji, listening? First off, if I’m in program
or aperture priority mode, I want to be able to specify
that under no circumstances do you ever go below the
minimum shutter speed. I’d rather have more noise at a higher ISO than a blurry shot, okay? You know, some kind of firm, minimum shutter speed specification in the Auto ISO settings. I’d like to be able to customize
the ratio, my own ratio, instead of using the default
one over focal length of the lens that’s in here. Basically, I wanna choose the number and then the camera would use
that number as the multiplier. Three, could we please have an ability to rename AUTO1, AUTO2, and AUTO3 to something a little more friendly like, you know, indoor church
or outdoor soccer practice? That would be helpful. That’s all for today. Thank you so much for watching. If you enjoy the video, please
give it a Like and subscribe, and I will see you again real soon. Take care. Exactly how are these calculations mate? (dog barking) – [Female] Hello.
– Hey. Is there any way the dog
cannot be going berserk? – [Female] No, it was just UPS. – Okay, they’re gone now? (laughs) – [Female] Yup.
– Okay, thanks. – [Female] Sorry.
– It’s all right. (exhales) (upbeat music)

  1. Please make Long exposure photography video for xt3

  2. It is a pleasure to hear so technical correct videos. BTW l'm a biggest fan of auto ISO. I prefer 160- 1600…
    Best wishes!

  3. Thanks for the explanation of this feature. I will be using the front command dial to control ISO and exposure comp. If I am using an AUTO ISO setting, does this front CD override that? Or do I have to just set the Auto ISO to Command in this particular case?

  4. I tried to follow your setting for DWATI for my X-T3 but was surprised to find that the MY portion of the menu was grayed out and not available. Do you know what I need to do to remedy this? I have been setting A and SS manually and using front command dial to dial in the ISO for exposure (the camera is in Manual when I do this).

  5. Thank you again for this series. It’s been very helpful and I have already taken what you passed on and started using the tips.

    The only downside is that you may have to do this all over again for the X-T4.

  6. Great video.
    At 10:58 is a perfect example of my frustration of using Auto ISO in Video mode. The flickering as it adjusts the ISO is such a drag.

  7. Please disregard my initial comment…..I know why the MY portion of the MENU was not available. When I get a few moments I will hopefully be able to set up DWATI. Thanks so much for your video…..very helpful as always.

  8. Helpful video and very good points made! 👍

  9. All the more reason we need IBIS 🙂

  10. Good stuff man, thanks for the vid as always a pleasure to watch your content!! Keep it up!!

  11. Just a thought/question in reference to TTL flash. The TTL seems to fight the Auto ISO.

  12. Mainly taking photos of the kids and holidays etc so definitely would prefer grainy photos over blurry. High Auto ISO ftw

  13. The reason for lowest shutter speed of 23mm is 1/34 is because safe shutter speed formula for handheld of 1/focal length is based on 35mm equivalent focal length, which 23×1.5 is 34.5.

  14. I do not like to use my xt3 above ISO 320, if I directly have photos in JPEG. Above ISO 320, the jpegs become flat. RAWs are different.

  15. Nice video

  16. You are cool

  17. 1 / (23mm x 1.5 crop) = 1/34.5 sec minimum shutter speed.
    With OIS, let’s say they gave you 4 to 6 more stops. But that could make subject motion blur a big problem. Therefore, it’s not clear how to decide the Auto min shutter speed with OIS lens. I think you just have to decide yourself with a non-Auto setting. Fuji could have given a fourth setting for OIS min shutter speed to prevent us from diving into the menus when we swap lenses between non-OIS and OIS lenses.

  18. How dare ups drop off a package while your recording lol. Some nerves

  19. Brother you dissected the XT3! This video is very insightful!!!

  20. UPS Guy the nemesis of dogs worldwide! 🤣😂🤣😂🤣

  21. Gem stuff! Short and clear!

  22. I know this "auto shutter speed" from my old Nikon F-801. The Nikon tried to get to the minimal shutter speed of 1/focal length in "P" mode. That was the "official rule of thumb" for full frame. I'm not sure but I think even the Nikon FG from my dad took that into account with the "P" mode.
    So for the Fujifilm, the rule of thumb should be 1/(focal length * 1.5). And in fact in your video, the camera chooses 1/34 while you have a 23 mm lens. So either this is a fortunate coincidence or the camera takes the APS crop factor in calculation (I guess the latter is what the camera really does =).

  23. 5:00 Maybe 1/34 takes in to account the crop rate of the sensor. Like on a FF camers it would choose 1/23. but if you multiply 23mm with 1,52 which is the Fuji crop ratio – you'll end up at 1/34 sec-.

  24. Thanks, so useful and so clear ! One question, why AE-Lock doesn't work for this configuration: Aperture manual / Speed manual / Iso Auto. Shouldn't the ISO be memorized ?

  25. Next fuji x-t5 on the iso dial: auto max, auto low. Great video again by the way. I really like your video’s. Keep up the good work!

  26. 👍Terrific revelations, especially “Min shutter speed” not being a “solid” limit. Other cams behave in a similar way. My Sony drives me crazy when it displays shutter speed lower than my specified “low limit” (in aperture priority using auto ISO). At least your Fuji displays ISO continuously as it changes in the display — my Sony shows ISO as “Auto” until shutter half-press when the cam selected numerical value is displayed until full shutter press or shutter release. Min shutter speed greyed out when cam is in Shutter priority mode. What settings take precidence can be a maddeningly fuzzy concept.

  27. Auto-auto goes for 1½:1, not 1:1.

    The dynamic range setting overrules the minimum ISO setting.

    Otherwise a good explanation 🙂

  28. Once again a fantastically constructed and very useful tutorial. I have often wondered where I was going wrong with auto ISO, and now I know! Thanks again Chris!
    Still looking forward to the studio / drawer labelling tour tho. 😜

  29. Another great video!!! Thanks for the info! I hope you can do a video on focus stacking as well 🙂

  30. I have the XT-2 and the Leica CL. The CL lets you set the minimum shutter speed to 1/f, 1/2f, 1/3f, and 1/4f. "f" being focal length in use. Very convenient. So far, I haven't noticed the camera go below how I set it. I really enjoyed the video on how ISO works. Thanks!

  31. Excellent video again. However with my Nikon D500 I can set a minimum shiutter speed of say 1000sec for faster action, not so with the Fuji X-T3. But then again I did not buy the Fuji fo serious sport action. (Adelaide South Australia). I also prefer manual ISO on the Nikon D500. PS ISO is really a misnomer, it really has more to do with sensor sensitivity. What is ISO on one digital camera to another..

  32. Awesome… Love learning when teacher is teaching in a fun way.

  33. awesome like usual, and this video to me was very helpful, thanks pal

  34. I doubt that will work for weddings, especially when taking pictures of the bride. Because when I take pictures of the bride, I expose for her dress, if you overexpose dress, that shot is basically ruined. Because you want to have details of the dress in the picture. I am almost sure that camera will be exposing for face, because you will focus on the face. But of course that would be great tactic to use in other situations. Thank you for putting out great videos!

  35. So is an xt4 on your buy list?

  36. Excellent video on a very important subject (to me, at least). FUJI: please listen to Chris!!!

  37. Oh man did you lose a lot of weight??

  38. I despise auto ISO on the XT3 because it never budges from the Max Sensitivity value no matter what I do so I simply do everything manually. I haven't found out why it does this.

  39. I didn't notice the dog nor would I have cared until you mentioned it… just saying!

  40. I’ve goofed around with just about every strategy with Auto ISO and I’ve finally figured out what works best for final image quality. I keep a max ISO of 3200 and min shutter speed of 1/60. I then set my exposure compensation dial to -2/3. In 90%+ of the situations I find myself in, this works perfectly. The result is typically an underexposed image taken at a lower ISO. For example, pulling up the the exposure +2/3 in LR on a 1600 ISO results in a noticeably cleaner image than one captured in camera at 2500. For the rare instances where i need to go above 3200 I switch over to full manual control and underexpose by a stop or more. In my experience, LR (or C1) does a much better job of recovering detail than what you can get in camera using a higher ISO. I’m looking forward to your ISO invariance video!! I’ve done some tests myself and was surprised by the results…

  41. Thank you for great vid 😍😍😍😍

  42. Love watching your videos. So pleased that you got over your original doubts and stuck with it.

    Still writing scripts?

  43. great idea

  44. So how do you lock your exposure with auto ISO? I found my XT2 would only lock the exposure by half pressing the shutter, but the AE-L button doesn’t work anymore.

  45. great expplanation

  46. Can you test your AFL and AEL buttons? You'll find that AFL works fine but AEL button seems to be not working in this mode! Meanwhile, half press the shutter button can still lock exposure… I know it because I've been shooting in this mode since I got my XT3. It's a little bit annoying because I shoot street photography and I would love to control exposure through AEL button. But I can't. Hope fuji will fix this inconsistency bug!

  47. Well i see now why most of my pbotos are blurry when i zoom 100% on it. 😑😏

  48. damn this video helps me a lot. After using my X-T30 for more than half a year, I still missing something. The auto ISO would be really helpful, cant wait to try it out. btw your explanations are easier to understand than other videos I came across. Keep it up!

  49. This is a fantastic video. Thanks so much for posting it. I've always felt confused by the Auto ISO settings in my Fujifilm camera. This helps tremendously. I'm now a subscriber. You make some great videos. Please keep up the great work.

  50. Which lens was used for initial shots ? Please always mention that 🙏🏻 I love your content but it kills the mood to not know the Lens

  51. Okay for stills but this camera has to be one of the worst for video in
    auto exposure, no smooth transitions very steppy

  52. I 100% agree!
    I use ISO 12800 max.

    People put too much thought into High ISO performance.
    As long as you can see the expressions on peoples faces that expresses the moment, I and the people are perfectly happy with it.

    Graininess should be viewed as a style rather than a failure. What really sucks is missing the moment!

  53. There are slso problems with Flash (I have the Godox 685 and 350). The results with Auto iso are not good at all. This is the only thing I have a problem with, otherwise the T3 is superb.

  54. To add on to your tactic, I Think exposure compensation dial should also play a role and be useful

  55. Hey PAL2TEC: great video!!! Thnx for it. But… how do you set AUTO2 and AUTO3??? Keep it up!

  56. Great to see you again dude

  57. I also use the DWATI method but I have never heard it called that. In addition you can still use the exposure comp dial to dial in your final exposure

  58. Nicely done!

  59. awesome, your explanation of these 3-settings (Auto1, Auto2, & Auto3) … always wondered when they came into play — in Program, Aperture, or Shutter priority … you have a method of instruction that even the inept can understand, thanks so much for the insight .. am now a better photographer (keep the good work coming).

  60. YES.. THANK YOU. I have been really kind of looking for an explanation for how this works since I do Street with my XT3 Aperture priority. But I use the Auto setting. I also don’t understand why it doesn’t say minimum ISO and maximum ISO. Great video. Thank you.

  61. The Fuji auto ISO makes sense on every aspect except for breaking out of the lowest shutter speed. It's almost perfect. I don't understand. #JustDoWhatISet

  62. Awesome video about a difficult topic that bothers many of us, I guess 👍🏻👍🏻

  63. Very good, thank you.

  64. Interesting topic and tips. Thanks for sharing!

  65. Great video Chris! You explained that well. DWATI. You’re so funny.

  66. I just received my new xt3 today. Can you tell me whether or not the grip batteries are charged while connected to USB-C? Couldn't find anything in the owners manual.

  67. You can actually put it on command and link it to a wheel. then you can chose your iso and go further and chose one of the 3 auto iso settings.

  68. Thanks, excellent video, as usual 👍

  69. 0:36 Господи боже мой, зеркало для отражения картинки с дисплея…мама дорогая

  70. 7 or 6 days left before the new Fujifilm X-T4 officially coming on February 26, Pal2Tech!!

  71. …crystal clear

  72. Yep I agree. That's how I control my shutter speed and ISO on my XT2. Fool me once…LOL!

  73. Worth pointing out Fuji's high ISO uses a different system, in reality it's often over a stop overstated compared to other makers
    I know as I tested a few next to other cameras. Very misleading IMO

  74. Auto ISO is the best way to determine the lighting in your shot when taking photos quickly before going into full manual to get your photos exactly right. I run and gun with auto ISO the majority of time until I settle into one location.

  75. After latest firmware update when turn on video ISO not working 😒😒

  76. Thanks for the video, and especially for calling out the difference in how Fuji interprets "max ISO" and "min shutter." I agree that's a very weird decision on their part to treat min shutter as a harder limit than max ISO.

  77. Hi, nice contend, when I put my XT3 to Auto ISO setting min 160 max 12600 min 1/60 my XT3 will sit on ISO 12600 no matter what. When I point the cam right into the sun it stays at ISO 12600. Don't know what to do.

  78. Hi, you are right! The image was taken by ISO 4000.

  79. That is very interesting. I didn't check that out on my own and I was Thinking that the MINIMUM shutter speed would be the MINIMUM.
    So, thank you for explaining.

  80. Your teaching style is always great. Can't wait to get a Fuji (xt3 or hopefully xt4). I need to upgrade because I have a G7 lol. Looking forward to my future Fuji so I can really apply what you're teaching here

  81. such an underrated channel.

  82. XT4 😂

  83. One thing most people don't realize or mention especially on YOUTUBE about the Fujifilm X Series Camera's is exposure ramping, what i mean by that is if you have your camera set to auto or Manual lets say manual mode, with aperture F9 and shutter speed 100 and ISO 1600 or even 400 no matter. and then you zoom in or out with your camera you will notice the Camera changing exposure briefly while your zooming in or out , as soon as you stop zooming in or out the exposure changes stop.

    I call it Exposure Ramping you will notice the flash on the LCD screen or viewfinder you will see the flicker of light / exposure change while zooming in or out..
    it seems that this only happens with Fujifilm X series camera's i don't know if it happens with other Fujifilm Camera's but i can tell it you don't happen with any other Camera brand ie NIKON CANON SONY, I never seen this before until i got a Fujifilm camera..

    I think it's a problem or flaw if you ask me why would you want to be recording video and see the screen flicker light while zooming in or out? i mean it's like doing video with a variable aperture lens and your at F2.8 wide angle and you start to zoom in and the Aperture changes to a higher number we all seen this, and we try to use lenses that are not variable aperture lenses, just for that reason doing video. It ruins the artistic value of video..

    So this is a problem no one has mention it or complained about it that i know of but i have to Fujifilm and they got back to me and said this is normal and part of how the camera works.
    I then asked is there a way or some setting i can set to prevent this they said no it can't be prevented..

    Well i find this unreasonable, and Fujifilm should address this problem they could possibly do this in firmware easy, but i yet to see any one bring this up if enough people brings this up maybe just maybe Fujifilm will do something i'm trying to get all the YOUTUBER's to post a video about it because we all know going out in public with something is a way to peek interest of the camera manufacture to fix a problem, other wise they won't lift a finger to do anything you can bet on that.

    no camera should be adjusting any part of exposure in full manual mode while trying to zoom in or out with your lens, by the way this happens in Shooting pictures mode too not just video.
    But this really only impacts video because it doesn't happen when your not touching the zoom, just only when you zoom in or out..

    all you fujifilm x series camera owners go and try and see if it happens to you, i'm sure it will inf act i know it will but check it out you will see what i mean..

  84. Good day! I have a question. I am in the position to buy an xh1 or xt3 for almost the same price. What would you advice someone going into photography and mainly shoots beach stuff, architecture and some travelling and small events?
    Former cam was shortly an xt-2
    BTW- love your energy sir!
